At histological sections of 16 human noses from the 3rd fetal month up to the newborn stage the continuous increase of collagen structures in the connective and holding tissue aging of the inferior nasal concha were investigated with conventional histological, polarisationsoptical and histochemical technics. It was stated that from the 3rd up to the 5th fetal month a mesenchyme in the process of changing is present and in the 5th fetal month a fibre texture like in adults can be seen. The ossification of the chondral frame work of the concha to a double lamella begins in the 5th fetal month, but isn't completely finished in the newborn. The concentration of neutral polysaccharides and glycosaminoglycanes increases with the onset of fiber formation and ossification.
